Compared with scattered abrasive with the same number grains, the removal rate is less.
The number of cracked dings in the workpiece surface decreases and the surface roughness become little to a certain value.
The number of cracked dings in the workpiece surface is little, the roughness rapidly decreases and become nearly unchanged at last.
When the grain size is big, high speed is chosen.
Grain type and grain size of polishing film.

Introduction The properties of nanograined intermetallics strongly depend on the grain size, the morphology of grains, the homogeneity of grain size distribution, the relative crystallographic orientations and the nature of grain boundaries [1,2].
Results Fig. 1 shows the variation of microhardness, HV0.2, against shear strain (γ) after processing by HPT for four different numbers of turns at (a) 473 K and (b) 573 K.
Fig. 2 shows XRD profiles for the samples processed at (a) 473 K and (b) 573 K after different numbers of turns including the initial powder mixtures.
The fraction of the Al3Ni intermetallic increases with increasing number of turns, i.e., increasing shear strain.
In addition, a peak broadening occurred as the number of revolutions increased, indicating the introduction of lattice strains, dislocation generation and grain fragmentation during the HPT processing [5,6].

Dependence of the density of samples from fine-grained concrete on the amount of calcium stearate 3.5.
Dependence of the strength of samples from fine-grained concrete on the amount of calcium stearate 4.
By creating a hydrophobic film around the pore space, firstly, it reduces the permeability of large pores, and secondly, it reduces the number of pores with a size of 10-100 microns.
It increases the workability of the mortar mixture, reduces the size and number of pores, and therefore slows down water absorption, practically does not affect the strength characteristics.
Study of the kinetics of water absorption of fine-grained concrete.

The pure volume of all grains should be as full as possible.
Silicon carbide in particular has been the focus of a number of research groups and organizations in the past 15 years especially in electronics engineering [1].
SiC increasing especially mechanical parameters of mixture because these materials have number 9 on Mohs hardness scale [3].
Grain curves determine the unambiguous amount of fine and coarse aggregate.
From overall view, using silicon carbide in cementious mixture is advantageous, especially in mechanical parameters because SiC materials have number 9 on Mohs hardness scale.

The affair number of transaction item set in data set is called supporting number, which is recorded as.
(2) Reducing the number of support degree computing, so the number is close to the frequent itemsets number
(3) Using the number of sub itemsets to get the maximum decomposition

These results show microstructure one of the sample for sample number 3 which exceed the highest average overall length A that become more globular with higher average grain size after the feedstock billets were re-heated to semisolid range temperature.
Table 3 shows average grain size measurements for microstructure of sample number 3 consists of area, perimeter, circularity, diameter and aspect ratio.
Table 3: Average grain size measurements for microstructure of sample number 3 before and after injection test.
At this time, grain spheroidization and coarsening were started when liquid phase at grains boundaries.
As the initial microstructure of feedstock billets in sample number 3 were surrounded by higher secondary phase content, it catalysed the formation of smaller α–Al solid grains.

Aluminum-copper alloys offer both high strength and excellent ductility suitable for a number of automotive applications to reduce vehicle weight; however, the alloys are difficult to cast because of their tendency for hot tearing.
Aluminum-copper 206 alloy has a number of potential applications to reduce vehicle weight, including automotive suspension knuckles, vehicle control arms, differential carrier parts, aerospace and military castings [1].
Image analysis of the samples yields the grain size plot in Fig. 4.
In addition, the SSM samples have finer grain structures.
Grain size of the representative liquid cast and semi-solid cast samples.

The surface morphology of the films showed more uniform sized grains.
While comparing the MgPc of films, it’s found the intensity of characteristic peak is high as the energy and number of laser pulses increase and the crystallize is monoclinic form is observed in β-form.
Table (2): Shows the grain size (D) that calculated from FE-SEM images.
Table (3): Shows the grain size and surface roughness values for laser pulsed energies (200, 300, 400, 500) (mJ).
FE-SEM analysis showed that the film morphology become homogenously distributes various structural parameters such as grain size ,surface roughness have been estimated ,reported and conclude that as laser pulsed energy increase ,grain size decreases.we also demonstrated that the number of laser shoot pulses play a significant part in the structure of the deposited thin films .

The number grain of the ferrite and austenite phases caused increase in hardness and strength within the stir zone.
There are a number of calculation methods, e.g.
Number of measurements in the weld metal was dependent on the width of recast and ranged from 7 to 11 measurements [11].
Secondary austenite is formed on the border of ferritic grains, which grew up to the volume of ferritic grains in the form of needles.
The dimensions of austenite grains in the recast resembled to the dimensions of austenite grains in the base material.

Introduction Quality of rice can be determine by moisture content, shape, chalkiness, whiteness and the number of broken rice grains.
Rice grains are considered as broken when their size is less than three-fourths of whole grains.
Normally, broken rice grains only have half of the value of whole rice grains.
Conventionally, farmers use the grain grader with separator which is big in size and expensive to separate the broken grains from the whole grains.
